flexrac Posted January 26, 2019 Author Share Posted January 26, 2019 Replaced Lilu and AppleALC to the most current version 1/24/2019 and audio is now working. I used the tools you attached @Jake Lo and extracted my DSDT I need to figure out how to use this info to reroute my audio devices. Front = headphones Dell internal speaker =internal speaker Rear port - single green connection = no sound Flexrac DSDT Optiplex 3050.zip I also tested sleep and it works perfectly only reason I'm fussing about the audio out is because I have this system attached to my 60inch in the LR and would prefer to have all cables attached in the rear Link to comment Share on other sites More sharing options...
